HAY AND GRAIN UNLOADEFL' SPECIFICATION forming part of Letters Patent No. 271,862, dated February 6 1883.

i Application filed September 2, 1882. (No model.)

to the annexed drawings, making a part of this specification, and'to theletters and figures of reference marked thereon.

Figure 1 of the drawings is a side view of Fig. 2 is also a side view in a Figs. 3 and 4 my conveyor. :{difl'erent position from Fig. 1.

This invention has relation to hay and grain conveyers and it consists inthe construction and novel arrangement of parts, as will be i hereinafter fully described and claimed.

1n the accompanying drawings, the letter A designates the body of the carrier, which consists of two'sides or sections, co, which are connected together by transverse rivets or bolts,

which may,when used upon an iron, a wooden,

or a cable track, serve as the pivots of the trackrollers c and of the sheave j. 1) represents the track,which is single, and may consist of wood, iron, or cable. The sides orsections a,when se- 0 cured together, present an opening, d, from below, which is at its mouth of rectangqlar form, having rounded corners, the walls of this opening inclining inward and upward to aterminal channel or recess, e,which also extends upward.

5 This. opening and channel aredesigned to receive thelooped upper end, l,of a pulley-block, j", which, when rising, enters therein and actuates the working parts. The loop' of the pulley-block is rectangular, and rounded on the 4.0 corners to fit the opening 0?.

Attached to a swivel, g, at the lower corner of that end ofthe carrier which isfarthest from the power is the operating rope or chain h, which serves to raise the load and draw the 4 5 same. This rope or chain passes from the fasteuing g, through the forked pulley-blockf, and underasheave, z, therein; thenceoverasheave, j, in the lower corner ofthe carrier nearest the power, and along the under side of the track,

ward said channel or recess.

over a pulley beyond where. the load isto be dropped to the point where the power is applied forhoisting and carrying the load. The looped pulleyfis therefore suspended on the v rope h, and is provided at its lower end with a swivel-hook, 70, for the attachment of the 5 hay-fork or other load.

Near the middle of the carrier, at one side of its channel or recess 0. and between the sides of the carrier, is pivoted a crescent-shaped carrying-hook, m, which is made heaviest at its upper end, which extends toward the channel or recess, and tends, when the hook is free, to withdraw its hooked lower end or beak from said channel or recess. The carrier-hook is therefore arranged with its concave side to- Upon its upper portion, somewhat set back from its upper end, is a projection or shoulder, a, which, when a load is being carried on the hooked end 2, is designed to engage a shoulder or projection, n, on the under side of a latch-bar,p, which is also pivoted between the sides of the carrier. When not engaged by this latch-bar the lower end 'or beak of the carrying-hook recedes from the recess or channel aim the carrier, its upper end at the same time dropping into said recess or channehin position to belifted by the 1 upper end of the looped pulley f when the latter is drawn up. In this action the pulley, in raising the upper end ofthe carrying-hook, also forces its lower end or beak, 2, through the loop of the pulley, in position to sustain the. same, with its load, independently ofthe operating-rope. The carrier is held while the load is being elevated by the latch-lever 19, one end of which projects beyond the carrier under the track in the direction farthest from the power. This end of the lever is beveled on its upper surface, as at s, and is formed with a projection, hook, or shoulder, q, which is designed to engage a latch-block, 1t, secured to the under side of the track. The latch-lever p is made heaviest at its inner end,which is formed with a longitudinal under recess or groove, 2;, and back of the same a shoulder or projection, n, 5 on the under side of said latch-lever, designed to engage respectively the upper end of the carrier-hook and the shoulder thereof. When with its load, its upper end pushes upward the inner end of the latch-lever and disengages the other end of the latter from the catch B, so that the inner end of the lever drops with the pulley,in its receding movement, to engage and firmly lock the carrying-hook in its engaged position, supporting the looped pulley and its load. By means ofthe operating-rope the carrier and its load are then drawn to the point of discharge, when the fork is tripped in the usual manner and itsload is let fall. Then the carrier is drawn back on the, track until the beveled end of the latch-lever strikes the catch-block, whereby the inner end of said leveris raised, unlockingthe cai-i'ier-liook,which automatically drops and releases the looped pulley, which is then allowed to descend for an other load.

Having described this invention, what I claim, and desire to secure by Letters Patent,-

v 1. The sectional carrier having the rectangular channel or recessed opening extending upward from its bottom, the crescent-shaped and top-heavy carrier-hook m, having the shoulder n, the latch-lever 10, having the shoulder n, and the longitudinal under recess or groove v v, the looped pulley-blockf, and catch R, substantially as specified. I

2. The combination, with the under grooved latch-bar having the shoulder at and the beveled catch end projecting from the carrierbo dy, of the top-heavy carrier-hook having the forwardly-projecting upper end and the shoulder at, and the catch block R, substantially as specified. In testimony that I claim the above I have hereunto subscribed 'myname in the presence of two witnesses.
